ok,

i stripped my ISCV, and cleaned it out with brake cleaner and air gun.


Tried the test with ign on (as Mike R advice )
, but with my s8 it dont do anything, so i pluged in my old p8 super 8, and Bang the ISCV does fine on the test, i also got 2 spare iscv's off a mate, cleaned them, and they do the same on the test, (open and shut fully 5-10 times wen ign is turned on)

So refitted my one, and Bang its now workin, so played around abit on the settings on the s8, and idle'n nicely, the only thing is the iscv seems abit slow to adjust the idle (not sure if thats normal, as i've never run it with it connected )

So gonna try the 2 spare ones, and see if there's a difference, and may be borrow my mate brand new one and go from there.

Here's a few pics of the 2 sorts i have, they are all 01 ISCV's
